IMPROVEMENT IN SPINNING-SPINDLES.

Specification forming part of Letters Patent N0. 209,199, dated October22,1878; application iiled June 24, 1878.

To all whom 'it may concern:

Be it known that I, JAMES C. STANLEY, of New Hartford, in the county ofLitchfield and State of Connecticut, have invented a new and usefulImprovement in Spinning-Spindles, and I do hereby declare that thefollowing is a full, clear, and exact description thereof and of itsmode or manner of operal tion, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, and making apart of this speciiication.

This invention is an improvement on that class of spinning-spindleswhich are self-oiling, or in which the oil is carried up around thespindle by its own rotation, similar to that described in Letters PatentN o. 181,804,

' granted to me on the 5th day of December.,

. quently a more uniform and easy revolution of it.

Figure 1 is a view, partly in central vertical section, of the spindleand the spinningrail in which it rests, the two being in properposition. Fig. 2 is a detached view of the spindle. Fig. 3 is a detachedview of the lower part of the spindle and its conical spirally-groovednut.

A is a portion of a spinning-rail, forming a part of the spinning-frame,and is a solid continuous piece of metal, and contains within itself aseries of chambers, a, each of which is a receptacle and holder of aspindle, B, and its bolster or easing b, which is nonrotary, and throughwhich support is given to the spindle, and it .also forms an oil-chamberto the spindle.

An oil duct, d, within the rail, and to which oil is supplied through acup, e, communicates with all the chambers a., so that all the spin-'held in position by setscrews C.

`The spindles B are itted with whirls f, and revolve within the holstersor casings b, which form bearings for the spindles, the spindles beingmade cylindrical for a part of their length, o o, corresponding inposition with the upper ends of their holsters or casings,

and for a distance to give a sufficient bearing in the holsters, andtapering the rest of their length, hot-h above and below suchcylindrical part.

To the lower ends of the holsters proper are screwed the holster endsb1, which carry or form the step-bearings g for the lower ends of thespindles. Y

The upper end of the bolster or casing b is formed into a cup, h, toreceive any overflow of the oil over the top of the bolster or casing,and leading from such cup are ducts z', which permit any oil gathered insuch cup to flowvfreely downward into the oil-chamber a.

A double-reversed cup, j, forming a part of the whirl, sits over the topof the oil-cup 7L., and prevents the escape of oil and the ingress ofdust. The oil is admitted to the interior of the holsters or ease b andto the spindle through openings lc k.

Around the lower end of the spindle, and just aboveA the bearing of itslower end, I place a conical nut, D, in which is a spiral groove, I.This nut revolves with the spindle B, and hy means of the spiral grooveeut therein continually lifts or forces up the oil around the spindle,thus causing a larger quantity of oil to circulate within the casing bthan would be effected by capillary attraction only. This nut D alsoacts as a collar to prevent, by its contact with the shoulders b2, thespindles rising out of their bearings.

The nut D should be of less diameter or smaller than the chamber inwhich it revolves, so as to have no contact with the sides of suchchamber. By this relative construction and arrangement' of the nut andthe chamber in which it revolves the spira-l groove of the nut itsbolster or casing b, of the conical spirallyis prevented becomingfilled, partially or grooved nut D, the several parts arranged Wholly,by any dust or sediment that may ensubstantially as and for the purposesset forth. ter the chamber with the oil or gather therein,

which would be likely to happen if the nut J. C. STANLEY. Was in closecontact with the sides of the A chamber. Witnesses What is claimed asnew is- S. D. LAW,

The combination, with the spindle B and I L. NELSON WHITE.
